By introducing this online and offline Coins concept into the “Cryptocurrency Creation and Distribution Using Dice Draw Result and Prehistory Data as Main Elements”, now the user of Coin system is able to claim back his/her Coins if his/her Coins is accidently lost due to handset broken, handset lost, etc.
The Online Coin can only be used when a user handset is online and connected to the Center so that a payment can be done.
While for Offline Coin, it can be used either user handset is online or offline. That is during user online make payment, if the Coin system found that the current Online Coins are insufficient to complete a particular payment, then the Coin system will automatically use the Offline Coins to complete this payment.
Therefore, in normal circumstances, a user A changed all its Coins to offline Coins will have no different with a user B just having Online Coins, for an online make payment. But there will be different when both users intended to make a payment when their handsets are offline.
Then, only user A can make an offline payment, while user B can’t make any offline payment, as user B did not have any Offline Coins.
